Why Does It Squeak When Braking?
2 Answers
The reasons for squeaking when braking: 1. Normal noise phenomenon. Brake pads are composed of iron plates, graphite, asbestos, etc. When they rub against the brake disc, some metal powder is inevitably produced, which can cause a squeaking sound when braking. 2. The brake pads have worn to their limit. The brake warning plate rubs against the brake disc, resulting in a metal-on-metal sound. If the noise is due to normal brake pad operation, there is no need to worry too much. Pressing the brakes firmly a few times or performing emergency braking in an open area can improve the situation. However, if the brake pads are worn, the braking effectiveness will significantly decrease, posing a serious threat to driving safety. In this case, it is essential to replace the brake pads promptly to prevent potential hazards.
It gives me a headache every time I hear squeaking sounds when I step on the brakes. This usually happens because the brake pads have worn down to their limit. The metal indicator starts scraping against the brake disc to produce a warning sound. Alternatively, there could be dust, small stones, or rust spots on the brake discs, especially after rain. Newly replaced brake pads might also make noise initially because the surface is still breaking in, which requires driving a few hundred kilometers. Additionally, insufficient lubrication of the calipers can cause the brake pads to stick and produce strange noises. I recommend not ignoring this issue because it can affect braking performance and lead to dangerous situations. I once nearly had an accident but solved the problem by replacing the brake pads in time. Regularly cleaning the wheel hubs can prevent dust buildup and extend the lifespan of the components. When getting your car serviced, it's best to choose a reputable shop to inspect the entire braking system, ensuring safety comes first.
